ATM over Ethernet and pseudowires

Hello.
Could somebody tell me if there is a Cisco Router that can work ATM over ethernet. This ATM circuits comming from an ethernet interface sholuld be transported as pseudowires through an IP/MPLS Backbone. Routers 12000 can do this? wich version do I need?
Thanks

Hi Narayan. Thank you.
I have now the following doubt. If we have the following topology:
lan-(CE)--ethe--(pe)--MPLS--(pe)--atm-(ce)-lan
Consider a lot of atm access at the right side, but we need to use only one vlan at the left side to connect all the remote atm sites.
You are telling me that we can convert the left CE in to a PE. But Can we maintain the router as a CE but terminating the ATM circuits (pseudowires) transported over one one vlan? ( atm over ethernet)
I appreciate everyting.

Internet over ethernet AND airtunes over wifi?

okay, so I have my airport express plugged into the sterio, but it's not permitted to be connected to the office network. So, I plug my macbook pro into the ethernet in the wall, and connect to airtunes over the airport. It plays fine for a few minutes then loses the remote speakers.
Is there any way to configure it to know that the only thing it does over airport is airtunes?

for anyone who might be interested, it just started working on its own.

Imac sharing my wireless to a PC over ethernet (and switch)

So I've got next to me an imac currently connected via a wireless N time capsule upstairs. I'm trying to get my PC hooked up to my Imac via "Internet Sharing". At this point I have...
Base station wireless-->Imac Downstairs-->Straight through to switch-->Straight through from switch to PC's NIC. I have a constant ping on my PC pinging my router's default gateway, and a ping on my iMac pinging the static IP address I set my PC to (Which is on the same subnet as the rest of my network).
Any ideas why they are just timing out and I have no connectivity?

IP address of my mac connection to the base station is 10.0.1.5, 255.255.255.0 subnet, router (Default gateway) address is 10.0.1.1
IP address of my iMac's ethernet going to the switch is 10.0.1.10, 255.255.255.0 Subnet. "Router: 10.0.1.1"
There's your problem.
You have the SAME subnet for both interfaces on the iMac. This is not valid, and will prevent internet sharing from working
Each interface has to be in a different subnet. If your wireless link is using 10.0.1.x/255.255.255.0 then your wired interface has to use something different. Choose either something else in the 10.x.x.x range (e.g. 10.1.1.x/255.255.255.0), or something completely different (e.g. 192.168.1.x/255.255.255.0).
Your PC will need to have an IP address in the same subnet as the iMac's wired interface and its gateway address should be the address set for the iMac's wired interface.

802.1x over ethernet and airport impossible together ??

I am connected to my University network (and to the internet) through a 802.1x network (Through Ethernet, not Airport).
I have an iPod Touch with which I want to connect to the Internet.
I went under Sharing, and created a Wireless network sharing the Ethernet internet. I was able to connect my Mac WITHOUT 802.1x to the internet for some time (authorised for a short time by the university) and was able to access the Wifi network and the internet with the iPod Touch.
However, as soon as I connect to the 802.1x network, Airport dismisses it's network, it just disappears ...
Why does it do that, can I prevent it and if not, is there any alternative for my problem ?

Yeah, I was just going on/hoping for... the 802.1x likeness.
Have you repaired Permissions lately?
Might try trashing these files & reboot...
/Users/nnnn/Library/Preferences/com.apple.internetconnect.plist
/Library/Preferences/SystemConfiguration/preferences.plist
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
/Library/Preferences/com.apple.sharing.firewall.plist
... of course you dont have to trash them, you can just move them to the desktop to drag back if it doesn't work.

Does Lookout have a driver for SLC 5/05 and 1500 over ethernet

Does Lookout communicate with the AB SLC 5/05 over ethernet and the AB 1500 via the Net DNI over ethernet ?

Several years ago (back in Lookout 3.8 days) there was ethernet for AB SLC-5/05, it was a choice on the pull down menu for the communications type. It works great.
then in the days of Lookout 5.X, NI removed the ethernet for AB SLC-5/05. I believe the issue was that some users were having difficulty in understanding the I/O addressing, expecially when they would have an analog input/output card in the chassie. The issue is that RSLogix 'neatly' organizes this I/O table for us, however, NI can only get the I/O table in its 'raw' form. And this caused confusion for users not experienced with how the I/O table is truly layed out. A user can experiment with a bench/test system and see how the I/O is layed out and get a good understanding. But a another method is to write the analog input value to a "N" file address, and use that in Lookout (remember only the I/O is the issue) Also, you can have Lookout write to another "N" file address, and in the SLC, move that "N" address to the Analog Ouput.
I still have a SLC file for Lookout that has the ethernet enabled (works with Lookout V5.x) but I bet Ryan can send you one if you need it.
I have upgraded to Lookout V6.2 and making a driver object to talk to AB SLC-5/05 on ethernet works great. (I love native drivers, and hate using RSLinx OEM to do OPC (for out ControLogix5000 processors)
If a person can work thru how I/O tables are truly layed out (one big matrix actually) go direct and dont' use OPC.
Remember, this isn't a fault/limitation of Lookout or NI, it is how AB layes out their I/0 table, and how the addressing we see in RSLogix is actually not the true representation of the actual matrix. (and this matrix is all that is actually available, AB just makes it more 'readable' because you (or who ever setup the chassie configuration) told RSLogix what cards are in which slot, so RSLogix can minipulate the table to show it to you more 'pretty'.
If NI would add a chassie configuration to the AB SLC driver, then this issue would not exist. But I don't think we want to do that.
Hope this was helpful!

Ethernet and wifi clashing?

hi, hope someone can help.
i have a brand new imac 21.5"
i run some IP cameras on a local wired network, 192.168.1.xx
these are picked up fine.
when i turn on the Airport, to connect to my wifi, the ethernet network drops.
is there a way to have both running? the airport configures using DHCP, and when i turn it on it connects with IP address 192.168.1.2
can anybody suggest anything, i'm at the end of my (very limited) knowledge about networks!! is there any info i've left out?
thanks

So you want to connect your iMac to two different Local Area Networks (LAN)? One over ethernet and the other over wi-fi? Or are they the same LAN with a connection for ethernet and wi-fi provided by the same router?

Connect monitor over Ethernet

Hi, I am trying to connect my MacBook Pro to my 30" Cinema Display in the other room. I do not want to spend hundreds on DVI cables to and then have to rewire my house. My house is already wired for Ethernet and I am wondering if it is possible to connect to the display through that cable. Thank you very much!

This device also does dvi over ethernet and it mentions dual link capacity.

Use Time Capsule over ethernet only?

Running Mavericks. Have a 2 TB surplus Time Capsule that I would like to use to back up an iMac using an ethernet cable between the iMac and the TC rather than wirelessly. (I am trying to avoid yet another Wi-Fi device on my Airport Extreme network and the reduced performance that comes with extending a network.) Indeed I have made this work per Bob Timmons prior posts by hooking the TC to both the iMac and temporarily to the Airport Extreme via ethernet cable.
Due to house configuration, it is not possible for me to permanently run ethernet between the Airport Extreme and the TC. In my experimenting, after setup I unhooked the connection between TC and Airport Extreme and the iMac and I thought the iMac was continuing to recognize the TC and backup to it over ethernet, but after a re-start I cannot get that configuration to work again.
1.     Do I understand that the design of the TC is such that it cannot be used as an attached ethernet hard drive for Time Machine backups unless it is at all times also connected to a [Airport Extreme] router?
2.     If No. 1 above is true, is there any wireless configuration of the TC that would allow for the benefits of ethernet connection to the iMac but not have the permanent router/TC ethernet connection?
3. Finally, if I am out of luck on ethernet only from the iMac, since I don't use the iMac wirelessly for anything, can a create a new network with the TC and have the iMac wirelessly connect with that without a permanent router connection?
Thanks very much

Thanks for your insightful questions and comments!
If you have an Ethernet cable connected to the iMac, the iMac will default to the Ethernet connection, even if wireless is on at the iMac.So, if you want to backup the iMac over wireless, you will have to manually disconnect the Internet Ethernet cable at the iMac every time that you want to back up the iMac. Once the backup over wireless is completed, then you will have to connect the Internet Ethernet cable again to the iMac.
Is this true? I was referring to the ethernet cable running between the iMac and the TC, not the main ethernet connection to my home network. My entire goal here has been to simply hookup the TC to the iMac solely for backup purposes via ethernet. However, you have convinced my I cannot do that without the TC also being connected to the Airport router at the same time., which I believe is not practical for the reasons below. So again, assuming that the iMac is connected to the TC via the TC's separate wireless network, is not the ethernet cable between iMac and TC not used - or will the iMac communicate to the TC via faster ethernet instead of defaulting to the slower wireless network?
The iMac is about 12" away from the iMac and I am not trying to hide it - I just want to use it as a ethernet backup disk!
I guess I'm wondering why.....if the Mac connects to the AirPort Extreme using Ethernet.....you cannot connect the Ethernet cable from the AirPort Extreme to the Time Capsule first, then connect another Ethernet cable from the Time Capsule to your iMac.
Then, the iMac is always connected using Ethernet, and you won't have to use wireless at all. You can backup over the much faster Ethernet connection. Everything will stay connected all the time.....no cable disconnecting.....and you have the best performance as well.
Good question! My newly remodeled house has an ethernet network wired throughout. One ethernet outlet per room. (The Airport Extreme router connects to a Comcast modem via the ethernet network, each in separate rooms. I was able to connect the TC to the Airport router using an 80 foot temporary cable running between rooms.) Maybe there is a way to have the TC "share" the iMac single ethernet port in the room that I am not aware of?   Appreciate your thoughts.
But, again....If the TC and iMac will be close to each other....why mess with wireless and cable swapping when you can do everything over Ethernet, and always stay connected to the AirPort Extreme network.
You are preaching to the choir. I don't want to use wireless at all for backup or even have it on for my iMac. The lack of a connection between TC and Airport router is what seems to be stopping me.
The TC will create both a 2.4 GHz and 5 GHz network automatically. The iMac will look at both signals and choose the best with which to connect. If the iMac has line-of-sight, or is in the same room as the TC, then it will likely connect at the faster 5 GHz connection.
And here is the last puzzle. Assuming that I cannot resolve the ethernet to router issue, I am today backing up to the TC (also connected via ethernet cable to iMac) via the separate WiFi network created by the TC. The backup has worked several times today. Despite this, Airport Utility reports that the TC cannot be found even though it was "previously part of the network." Any ideas on that one?
Thanks

Internet over ethernet, none over Extreme Base Station

I have optical cable to the house (no modem involved). When I connect directly to my mac, the cable company hands out a 64.xx.xx.xx IP address and I get blazing internet. When I connect to the AEBS it hands out a 10.xx.xx.xx IP address (I don't remember ever seeing the cable company hand out that kind of IP address before). Everything appears as if it should work, but I get no internet. The AEBS is set to share a single IP address using 10.xx.xx.xx addressing. The cable company has MAC addresses for both the iMac and the AEBS, so it should work. Everything was working before macworld... any thoughts? Much appreciated.
17" iMac G4 Mac OS X (10.4.4)

Thanks Don.
Before yesterday, the airport extreme base station (AEBS) was connected to my cable from the internet company and working just fine (receiveing a valid IP address and all). Yesterday, I get home from Macworld and my wife tells me we haven't had internet. Upon investigating, I find that the IP address that my AEBS is getting over DHCP is in the 10.xx.xx.xx format. My AEBS is still connected to the cable from my ISP and my computer is getting a full reception over my network with the AEBS, but no internet. I then connect the ISP's cable directly to my iMac over ethernet and PRESTO! a valid IP address in the 64.xx.xx.xx format and internet. My ISP tells me it's probably my AEBS. Today I hard reset the AEBS, re-configured it and got the same negative result (an IP address in the 10.xx.xx.xx format). I have an airport express (express) and decided to try that. I reconfigured it as a base station, and it worked...temporarily. Initially I got a valid IP address in the 64.xx.xx.xx format, internet worked great. I moved it around the room a couple times trying to find an optimal location and it started having the same problem as the AEBS, the only IP address it got from my ISP was an invalid or non-working IP in the 10.xx.xx.xx format. The only similarity between the "outage" of the AEBS and the express is that they were plugged into the same outlet when they went "out". My wife said that yesterday, prior to the AEBS going out, it had accidentaly been unplugged from the wall, and then immediately re-plugged. I'm convinced it's either a power surge issue of some sort which fryed them both (except I am getting an IP address, albeit an imperfect one), incompatible firmware, a virus, or my ISP... I'm really hoping it's the ISP.

Both ethernet and wireless time-out trying to connect

I'm having a problem with getting my laptops' IP assigned by dhcp. Both over ethernet and wireless.
I have no problem connecting to my WPA connection at home, but now I'm at my parents for a week or two, it refuses to connect to their WEP network.
To connect to my WPA network I run this script from rc.local, which works fine on startup.
ifconfig ra0 up
iwconfig ra0 essid *********
iwconfig ra0 ap **:**:**:**:**:**
iwconfig ra0 rate auto
iwconfig ra0 channel auto
iwconfig ra0 mode Managed
iwconfig ra0 txpower auto
iwpriv ra0 set AuthMode=WPAPSK
iwpriv ra0 set EncrypType=AES
iwpriv ra0 set WPAPSK=***************************************
iwpriv ra0 set TxRate=0
dhcpcd ra0
So for the WEP network, I have commented all that out and changed rc.conf like so:
lo="lo 127.0.0.1"
eth0="dhcp"
ra0="dhcp"
wlan_ra0="ra0 essid ***** key *******************"
WLAN_INTERFACES=(ra0)
INTERFACES=(lo eth0 ra0)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
But when I try to connect it just returns "Error, ra0: timed out".
I have also tried modifying rc.local (appropriately i think), but that seems to time-out too.
This wouldn't be so bad if I had the option to connect by ethernet, but that doesnt work either! It also times out, just like the wireless. I don't think it is the router, as all the other computers in the house work fine, both wired and wireless. But I don't think it's a driver issue either, as I can see all the AP's in kismet, and also I used the ethernet port when I first installed Arch a couple of months ago. I assume it's dodgy config files or clashing commands or something, but I've looked in the wiki and other forums etc, and I can't see what I'm doing wrong.
Any help would be very appreciated.
Thank you.
Paul

Make sure about the addresses for the LAN the router at your parents is using - they are not necessarily the same.

IP over Firewire AND Ethernet connected cluster?

Does anyone have any experience with IP over Firewire and Qmaster? What I'm trying to do (for now) is to have a file server connected to a bunch of Firewire HD's, then that connected to two other macs via IP over Firewire, and all that be a cluster.
The file server is the controller. Or I want it to be at least. Connected to this cluster are two workstations, connected to the file server via Ethernet.
So it's File Server with several external Firewire HD's connected to it with the video data. Connected to this file server are two macs via IP over Firewire which will be services only nodes. Connected to ALL of this over ethernet are two editing workstations. Qadmin can't seem to see the two mac nodes connected via IP over Firewire.
The problem is that Qadminstrator can't see the two macs connected to the file server via IP over Firewire. I'm wondering if for some reason data can't go from Ethernet to IP over Firewire and back again.
Any tips or suggestions? I'm just about out of ideas for now.

I was also NOT ABLE to use both nodes connected in a MIX of ETHERNET and FIREWIREover IP.
I WAS able to get a 4 x NODE cluster working using SHAKE & COMPRESSOR/QMASTER using all GbE EThernet - I went out and bought a cheap 8 x PORT ethernet GbE hub and all my problems went away.
HEre's what I had initially and what I did and it DIDN'T work consistently..:
Hardware Initially:
• g5 QUAD and 2 x MBP Dual Core 15's + 1 x MBPDC 17inch.
• G5 QUAD GBE1 connected to #1 x MBPDC 15 on its EN0 with cable
• G5 QUAD GBE2 connected to #2 x MBPDC 15 on its EN0 with cable
• G5 QUAD FW0 connected to 1 x MBPDC 17 on its FW1 with 6 pin FW cable
• G5 QUAD is set as CONTROLLER+SERVICES
• MBPDC's are all SERVICES ONLY.
• thus 3 x SUBNETS
SETUP#1- problem symptoms
• via QMASTERADMIN - G5 CONTROLLER could see MBPDC 17 and ONE of the MBP15;s but not all of them.
•tries various configs on each FW and EN0 for boths FW and EN paths.. never consistent view..
• removed some FW disks from FW400 path that were attached to CONTROLLER G5 host ... could then see ALL as a MIX of THERNET and FW. (Same happens using FW800 - although avoided this because of sperious DISK issues wth external FW800 disks on G5 QUAD).
• created cluster (not a quick cluster)- sent simple long I-FRAME based DV-PAL to smaller DVPAL) codec test to compressor and set the CLUSTER to the QMASTER on I defined.
• set QMASTER controller sys pref to use ALL NETWORK PATHS and disbaled the AIRPORT subnets on each MACHINE)
• PROBLEM was only G5(controller+services) and TWO of the services nodes (MBPDC's) were processing - NEVER all three! It didn't seem to matter what IP path was onnected (EN or FW).
• - all the above was a NO go waster of time. (aggh)
so..
HARDWARE SET UP #2 and what worked first time!
• purchased 1 x GBE Ethernet hub (8xport) w/P/supply and four 1m ethernet cables
• g5 QUAD and 2 x MBP Dual Core 15's + 1 x MBPDC 17inch.
• G5 QUAD GBE1 connected to GBE HUB
• #1 x MBPDC 15 on its EN0 with cable to GBE HUB
• #2 x MBPDC 15 on its EN0 with cable to GBE HUB
• #1 x MBPDC 17 on its EN0 with cable to GBE HUB
• G5 QUAD is set as CONTROLLER+SERVICES
• MBPDC's are all SERVICES ONLY.
• thus 1 x SUBNET....!
WORKS EVERY TIME First time
• all machines work to render or transcode.
• for SHAKE RENDERING, each CPU has a process.. so there seems to be as many as (4 x 1)+2 + 2 + 2 rendering processes at any one time.
• less for COMPRESSOR as one per HOST (4 in my case)
Also.. in QMASTERADMIN - always:
• have the SOURCE and TAGET disk volumes|directories ou need MOUNTED (NFS works for me) and
• set to NEVER COPY.
• set QMASTER sys prefs/Advanced/"USe NEtwork Interface = EN0 (or whatever one you want to use. 'd imagine that a FW hub would also do the job (IPoFW).... but for me I had all free ETHERNETs NICS so I used them.
• oh .. enable all your airports NICS.. .. in the above QMASTER wont use this subnet.
This speeds the WORKFLOW up enormously because the source material does not have to be COPIED to each host (well I think that what it means).
So the solution in my case was to have ALL the HOSTS on a SINGLE subnet..
works for me.
hope that helps

Access TC wireless and over Ethernet same time possible?

Is it possible to use TimeCapsule with my Powerbook wireless over Airport and my MacPro connected with Ethernet Cable at the same Time and also extend the Network wit an Airport Express?

Not sure I totally understand your printer setup, can you give more details? Is it a USB printer, or some kind of built-in wireless printer?
Is there some reason why you can't

As far as I know you can only have one internet interface active at a time, but not totally sure. Is the wired speed that much better than the WiFi, or what's the reason you need the Ethernet cable?

Using DynDNS and Sharing disks over Ethernet WAN port

I am having issues accessing the AirDisk from outside my LAN. So here are the steps that I have taken:
In the AirPort Utility, I enable "Share disks over Ethernet WAN port".
Created a DynDNS account at http://www.dyndns.com so my hostname points to my IP address.
After reading a bunch of threads, mainly this one below, there are a few conflicting issues.
http://discussions.apple.com/thread.jspa?messageID=4105319
Someone mentioned you have to Setup Port Mapping to open up Personal File Sharing. But another said you don't have to set up Port Mapping. Well if you do, you're gonna run into a problem. This Apple article states you have to use a different port: http://docs.info.apple.com/article.html?artnum=305183
Someone said Remote Access only works via AFP not via SMB. Is this true?
Also do I have to enter my DynDNS hostname into the wide area bonour tab in the advanced tab?
What am I doing wrong?
Macbook Mac OS X (10.4.8) Airport Extreme N

Are you aware of any DynDNS-like service that support Wide Area Bonjour?
None at the moment. One might hope that Apple's .Mac service would make use of it, but I don't think Apple has announced anything about that possibility.
Or as a practical matter is this a technology that only appears at the moment in private installations of OS X Server?
I've found the version of dnsextd that ships in Mac OS X 10.4 (not just the server version) to be a bit flaky. One hopes it will work a lot better in Mac OS X 10.5.
But since the AEBS doesn't support DynDNS update, as other routers do, it ends up requiring a server after all.
Wouldn't it be nice if DynDNS and similar services allowed you to configure DNS resource records manually? That way, it wouldn't matter what your home gateway/fileserver was capable of doing— you could just edit your DNS zone accordingly.

IP over Firewire and ethernet at the same time?

Is it possible to use both IP over Firewire and ethernet at the same time?
I want to use my TB hard drive attached to one Mac via Firewire 800 to backup another Mac also attached to the same drive via Firewire 800. I can only mount the drive on one machine at a time so I need to share it out to the other Mac. It works great if I set it up to do strait IP over Firewire, with static IPs, but that means I can't connect to the internet because my ethernet connection on both machines becomes the secondary connection method. Similarly, if ethernet is primary then I can't connect via Firewire. Is there a way to set it up so the Macs will know which method to use depending on the IP address?
I am using 10.5.1 on both machines.
G5, 1.8 GHz, 15.GB RAM
MBP, 2.4 GHz, 4GB RAM
Thanks!

Certainly.
In the network control panel I set Built-in FireWire to the top of the service order list, followed by Built-in Ethernet.
Next, I set Built-in FireWire to Configure Manually with the address 192.168.1.xxx and the Subnet Mask to 255.255.255.xxx, making sure the Subnet Mask is set the same on both machines and that the IP address is different on both machines and different from the Built-in Ethernet addresses.
I applied the settings, turned on Sharing on both machines, then mounted whatever shared drives I needed by connecting to the other machine using the FireWire IP address.
Now I am able to share drives using FireWire 800 - which works great when used with Time Machine - and still use my normal ethernet to surf, etc..

Ethernet over WDM and SDH

How do we manage ethernet circuits over WDM and SDH transmission network? What all OAM tools are available for managing and diasnosis of these circuits.

EoSDH is the term used for transporting ethernet frames over a SDH transmission network.If you can remember SDH, one way this can be achieved is using Virtual Concatanation. Here, n x VC12s are concatanated to get the required speed. ex: if n=5, the speed is 10Mbps.(VC12=2Mbps).(i.e Ethernet frames are put inside the VC12 container and transported.)The SDH equipment will give the customer a normal RJ45 Ethernet interface and in the back end, the no. of VC12s corresponding to the Ethernet speed is concataneted and transported over a STM-1/4/16/64. On the other side, the concatnated VC12s are identified and the Ethernet farmes inside the VC12s are mapped on to the Ethernet interface.
If you see the end to end circuit, you will see ethernet. so normal tools used for Ethernet troubleshooting can be used. SDH troubleshooting tools can be used to test the transport part. There may be tools which can troubleshoot moare than this.
